SWING-LETREE AND DOUBLE'IREE.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed January 14, 1908. Serial No. 410,777.

To all whom it may concern:

Be it known that I, GEORGE P. SIMPSON, a citizen of the United States, and a resident of Marysville, in the county of Fremont and State of Idaho, have invented certain new and useful Improvements in Swingletrees and Doubletrees, of which the following is a specification.

This invention is an improvement in swingletrees, doubletrees, and the like; and consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawing Figure 1' is a top plan view of a swingletree embodying my invention and showing the several skeins or sections with the overlapping portions provided with lugs for engagement by the centerv band. Fig. 2 is a detail perspective View of one of the skeins or sections shown in Fig. 1. Fig. 3 is a detail view illustrating the center band shown in Fig. 1. Fig. A is a top plan View showing a somewhat different construction at the center of the swingletree. Fig. 5 is a cross-section through the center band shown in Fig. 4, and Fig. 6 is a detail perspective view illustrating the means for connecting the inner ends of the skeins shown in Fig. 1-.

My invention is manifestly applicable to swingletrees, doubletrees, neck-yokes and similar constructions, and has for an object to provide in connection with a body A of wood, reinforcing skeins B fitting over the opposite ends of the body A, and extending inwardly to the center thereof and provided at their inner meeting ends with overlapping portions B which lap alongside each other and are provided at their extremities with upturned portions B which form bearings for the center band C whose ends are separated and made half-round in cross-section and threaded to receive the nut D whereby the center band is secured upon the skeins in such manner as to connect the same at their central portions and to hold the skeins securelyupon the body A. At their ends the skeins B are threaded to receive the end bands E, which may be provided with loops E, and are screwed upon the outer ends of the thimbles, thus forming a secure connection with the thimbles, and binding the same firmly upon the body A in the use of the invention.

The construction is simple, easily applied,

protects the rear side of said body when the latter is used as a swingletree against injury from coming in contact with the wheels or other portions of the running gear of the vehicle.

In Figs. 4, 5 and 6, I illustrate a somewhat different construction in which the skeins are fitted on the ends of the body, as in the construction shown in Fig. 1, and are threaded at their ends to receive the end bands and are provided at their inner extremities with upturned portions or lugs for engagement by the fastening device which holds the skeins upon the body. In this construction, however, the fastening device is somewhat different from that shown in Figs. 1, 2 and 3, in that it includes the split link F passing through perforations in the upturned lugs and bent to connect the opposite skeins, and the center band G passes around the body and has a portion fitting between the upturned lugs and engaging with the inner portion of the band F.

It will be noticed from the foregoing that in both constructions shown in Figs. 1 and 4L, the skeins are arranged at their outer ends for the reception of the end bands and are also provided at their inner ends with upturned portions and lugs, and the fastening means extends between the lugs and operates to secure the skeins upon the body portion.

Manifestly the broad ideas of my invention may be carried out by the construction shown in Fig. 1, or by that shown in Fig. 4: without departing from some of the broad principles of the invention.

I claim 1. The improvement in swingletrees, doubletrees and the like herein described, comprising a body, skeins fitting on the ends thereof and having at their inner ends portions lapping past each other and provided with upturned lugs, and a band encircling the body portion and fitting between the lugs of the opposite skeins and having at their ends extended half-round portions threaded to receive a fastening nut, a fastening nut screwed on the said ends of the band, and end bands screwed on the ends of the skeins, substantially as set forth.

2. A swingletree, doubletree or the like, comprising a body portion, end skeins fitting thereon and having at their inner ends portions lapping past each other and provided with upturned. lugs, and a band extending around the body portion and fitting between the lugs of the opposite skeins and adapted to be applied to and removed from the skeins withoutdisplacing the lugs thereon, substantially as set forth.

3. A swingletree, doubletree or the like,

comprising a body, skeins'fitting on the opposite ends thereof andcomposed of plates bent at their outer ends into cylindrical form and'tapered thence toward their inner ends, means connecting the skeins at their inner ends, the outer cylindrical ends of the skeins being threaded, and end bands screwed on the outer ends of the skeins, the latter be ing divided throughout their length, jsubstantially as set forth.

4. A swingletree, doubletree or the like,

comprising a body, skeins fitting thereonand lapping at their inner ends past'each other and provided at their said inner ends with fixed upturned lugs, and means securing the skeins together at their inner ends and ex;
